By famous I guess you mean a politician or actor/actress/singer/celebrity.
When I lived in NYC, we had a visit from a woman who was running for mayor at the time in the early 70's. Her name was Bella Abzug. Now, she was the politician, and alongside her was someone supporting her, no other than Barbara Streisand. So I got to see her on top of a truck (open van?) and everyone was calling on her to sing a song, lol. She had the most flawless skin I had ever seen on a person, like porcelain. A great singer and actress, my brother was in love with her. He had bought an album for her to sign, but she shook her head no. :D She later asked for a "piragua" which is shaved ice with fruit syrup on it, and someone got her a grape one.
Later on I also met Tony Hernandez, a former sports reporter from Channel 7 News. He was a hunk! I saw him on a movie theater line I was on and couldn't take my eyes off him. He and his date later came on in after all had been seated, in the dark.
Dark Shadow fans, on a school trip to Central Park and the zoo there, I happen to see Denise Nicolson, who played Amy on the show. I was a huge fan of that show and came running home to watch it every day after school.
Let me add here a small note: I also met the actress Lucy Lui, outside a movie set where they were filming a movie called Lucky Number 7. That movie set was there for a few days, and all that was filmed was a scene inside the video store. She came out as they were done with a scene, and passed in front of me and my daughters. There were tents set up so that the actors had food available. It seemed like the whole town was there, excited that a movie was being filmed right on the main street of where I lived.
